摘要： A control valve including a valve body, a chamber arranged inside the valve body, a fluid inlet, a fluid outlet, and a closing arrangement for regulating the flow of fluid from the fluid inlet to the fluid outlet via the chamber. The closing arrangement has a closed state in which no fluid, or only a leakage flow, is allowed to flow through the chamber, a first open state in which fluid is allowed to flow through the chamber, and at least one second open state in which a lower flow of fluid is allowed to flow through the chamber compared to when the closing arrangement is in its first open state. Between the closed state and the second open state, the closing arrangement is configured to allow fluid to flow through the chamber in accordance with a first valve characteristic function.

摘要： A valve having a balancing function for a fluid distribution system. A valve closing member is movable between a closed position and a fully opened position. An actuation device is provided for changing the position of the valve closing member. A control unit is provided and includes an electronic memory adapted to receive and store an opening limitation value, the opening limitation value being representative of a selected intermediate position between the closed position and the fully opened position of the valve closing member, wherein the control unit controls the actuation device to limit the movement of the valve closing member to positions from the closed position to the selected intermediate position. Also, a valve system and to a method of operating a valve.
